• Dolby Professional Reference Decoder DP580

    The first reference decoder for Dolby TrueHD, the Dolby DP580 assists broadcasters and manufacturers in the adoption and deployment of all Dolby audio codecs. It also performs comprehensive monitoring and logging functions.

    A Powerful and Versatile Tool for Testing and Quality Control

    The Dolby® Professional Reference Decoder DP580 allows you to monitor streams along multiple points of the broadcast chain.

    It provides a detailed analysis of Dolby audio streams, making it ideal for broadcast trials and manufacturers' test environments.

    Comprehensive Decoding, Monitoring, and Analysis

    As the first reference Dolby TrueHD decoder, the Dolby DP580 enables validation of associated Dolby TrueHD signals encoded in the Metadata-enhanced Audio Transmission (MAT) format—the first time this type of validation has been available for any testing environment.

    The Dolby DP580 also monitors the enhanced features of Dolby Digital Plus™, including secondary audio bitstream mixing and 7.1-channel decoding. It provides a real-time reference tool for generating signals for Dolby TrueHD, Dolby Digital Plus, and Dolby Digital.

    Quality Control and Loudness Monitoring

    With the Dolby DP580, you can perform quality control at any point within your headends. It also enables monitoring, display, and logging of all audio-related metadata.

    Flexibility and Versatility

    The Dolby DP580 also includes support for HDMI® with Extended Display Identification Data (EDID) device emulation, allowing emulation of HDMI repeater/sink devices such as A/V receivers and HDTVs. The DP580's many additional features include:

    • Monitoring capabilities for emulating set-top box behavior in QC environments
    • Consumer Emulation mode for Dolby Digital Plus and Dolby multistream decoders
    • Error detection and information logging
